Got to spend a day with Codex-5.3 and won $30'000! @julaiti_a and I just won 2nd place at the OpenAI Codex-5.3 Hackathon. $30K in API credits; pitched to @gdb, @thsottiaux, @sonyatweetybird, @lennysan, and @steipete; @sama attended our final presentation. Dream day. The best part? One hour before the deadline, nothing was working. Even coding agents perform best under pressure. Project takeaway: coding agents will soon be accessible to non-coders. E.g. your chatbot will be able to integrate your favorite tools on demand. Thanks to the judges, @OpenAI and @cerebral_valley for hosting an excellent day!

@OpenAIDevs Thanks for the excellent day! Really enjoyed hacking with everyone, good vibes!

🥇 OpenCortex • Yann Bilien and Vineet Reddy built a scientific collaboration platform where humans and AI agents submit research ideas. • Agents then work on real datasets to generate complete scientific papers with citation verification and quality scoring 🥈 Evy • @bosma_seb and @julaiti_a built a dynamic tool integration platform using Codex to dynamically create and integrate new tools. • Ask Evy to use any tool as you work, and if the integration doesn't exist, Codex builds it on-demand. 🥉 Paradigm • @majermaks and @zaiste built an adaptive development environment. • It analyzes your Codex conversations and automatically sets up "10x developer" workflows, creating skills for repetitive tasks so you get the memory right out of the box.

I have a guest essay in @nytimes today about autonomous vehicle safety. I wrote it because I’m tired of seeing children die. Done right, we can eliminate car crashes as a leading cause of death in the United States @Waymo recently released data covering nearly 100 million driverless miles. I spent weeks analyzing it because the results seemed too good to be true. 91% fewer serious-injury crashes. 92% less pedestrians hit. 96% fewer injury crashes at intersections. The list goes on. 39,000 Americans died in crashes last year. More than homicide, plane crashes, and natural disasters combined. The #2 killer of children and young adults. The #1 cause of spinal cord injury. We’ve accepted this as the price of mobility. We don’t have to. In medicine, when a treatment shows this level of benefit, we stop the trial early. Continuing to give patients the placebo becomes unethical. When an intervention works this clearly, you change what you do. In driving, we’re all the control group. Cities like DC and Boston are blocking deployment. And cities are not the only forces mobilizing to slow this progress. It’s time we stop treating this like a tech moonshot and start treating it like a public health intervention that will save lives. Link to article below. 👀 this video of Waymo cars evading crashes with people and vehicles. I especially note the ones that require it having a 360° view. My sincere thanks to Alex Ellerbeck and @acsifferlin for their wisdom and sure hand in editing this piece.

OpenAI Declares 'Code Red' to Fight Google's Gemini Surge Sam Altman is halting initiatives like ads, shopping, health and personal assistants. The immediate directive: improve ChatGPT's core experience, focusing on speed, reliability, personalization, and the ability to answer more questions. Why the panic? After Gemini saw a large bump in usage in September, they've continued to grow rapidly with the launch of Gemini 3. Meanwhile, OpenAI has seen their numbers plateau. While OpenAI still holds a substantial lead in DAU, they are not used to seeing growth flatline. The momentum shift is forcing a dramatic refocus. Ultimately, Bobbi thinks this fierce AI battle is a massive win for users and AI apps, driving better models and value sooner.

Welcome to the Brita filter economy. The internet gave us endless options. AI is giving us endless content. Now, more than ever, we need filters. Or as @NickOfNewYork says: content is king, but curation is queen. I’m convinced AI can (and should) help fix the noise it’s creating. More on that soon, stay tuned. Speaking of curation, I recommend checking out TBOY. Nick and Jack's mix of market stories and original takeaways never disappoints and always leaves me energized. #Curation #HYHTBOY #AI #Productivity
